ElasticSearch学习之(八)--简单ES项目构建

该博文主要描述springboot 集成ES7.3.0版本的项目构建，以及简单的数据同步功能实现。废话不多说直接上干货！

1. 初始化springboot项目，引入elastic search 7.3.0的pom依赖。

<!--elasticsearch相关依赖--> <dependency> <groupId>org.elasticsearch</groupId> <artifactId>elasticsearch</artifactId> <version>7.3.0</version> </dependency> <dependency> <groupId>org.elasticsearch.client</groupId> <artifactId>elasticsearch-rest-client</artifactId> <version>7.3.0</version> </dependency> <dependency> <groupId>org.elasticsearch.client</groupId> <artifactId>elasticsearch-rest-high-level-client</artifactId> <version>7.3.0</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.55</version> <scope>compile</scope> </dependency>

2. 完善ES的相关核心配置

######################ES集群库配置###################### elasticsearch: ip: 127.0.0.1 port: 9200 clusterName: elasticsearch_lgh #username: elastic #password: search

3. 初始化ES的核心配置类

@Configuration public class ElasticSearchConfig { @Value("${elasticsearch.ip}") private String ip; @Value("${elasticsearch.port}") private int port; @Bean public RestClient getRestClient(){ return getRestHighLevelClient().getLowLevelClient(); } @Bean public RestHighLevelClient getRestHighLevelClient() { List<HttpHost> hosts = new ArrayList<>(); for(String s : ip.split(",")){ hosts.add(new HttpHost(s, port, "http")); } RestClientBuilder builder = RestClient.builder(hosts.toArray(new HttpHost[hosts.size()])) .setHttpClientConfigCallback(httpClientBuilder -> httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider)); return new RestHighLevelClient(builder); } }

这样springboot项目就成功集成了ES，正常启动项目即可，下一篇为大家奉上如何使用代码完成读取数据库的数据写到ES当中。
